LPX-8.0-7.8-C 8 mm Dia. N-BK7 Image Grade Plano-Convex Lens; EFL=15mm Uncoated

The LPX-8.0-7.8-C is an 8 mm diameter, plano-convex spherical lens made from N-BK7 glass, a popular material in the optical industry due to its excellent optical properties. This lens, sourced from CVI Laser Optics, is an image grade component, indicating its high quality and suitability for critical applications.

The lens has a focal length (EFL) of 15mm, making it suitable for use in systems where a moderate level of magnification or reduction is required. The plano-convex design, where one side is flat and the other is curved, is a common configuration in optical systems due to its simplicity and versatility.

The geometry of the lens includes a thickness of 2mm at the edge and 3.1mm at the center. The radius of curvature (R1) is 7.8mm. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors. However, uncoated lenses can provide excellent performance in many applications, especially where cost or simplicity is a concern.

The lens is designed to work at a wavelength of 546.1nm, which is in the green part of the spectrum. This wavelength is often used in optical systems due to its visibility and the availability of high-quality laser sources at this wavelength.
